Seven-Channel Modbus TCP/IP Ethernet Data Acquisition Modules

DGH Corporation announces the D7000 series of seven-channel analog input smart data acquisition modules that communicate using the Modbus TCP/IP Ethernet protocol. The D7000 series consists of modules that measure voltage (+/-25mV, +/-50mV, +/-100mV, +/-1V, +/-5V, +/-10V), current (+/-20mA), thermocouples (J, K, T, E, R, S, B, and C) inputs and a universal module that accepts all of the above.

The D7000 series can be connected to any 10/100Mbps Ethernet port. The measurement resolution is 16 bits. Accuracy is +/-0.05% of FS max. Conversion rate is up to 25/s. Input to output isolation is 500Vrms. Input burnout protection is 250vac. The modules contain a customer programmable digital filter. All scaling, linearization and calibration and communications values are stored in EEPROM, which maintains these values even after power is removed.

The D7000 series also includes a two-channel analog output module with 12 bit DAC resolution, programmable voltage or current outputs at 250 conversions per second. Modules with 15 bit digital inputs, 15 bit digital outputs and 7 digital inputs with 8 digital outputs are also available.
